This two-sided fabric sleeve slips under a door and grips both faces, so it moves with the door instead of getting kicked out of place. It fits doors up to 38 inches and covers gaps up to about 1.4 inches, with no adhesive and no screws.
If you rent, this is the door product to start with. Nothing sticks to your door, nothing screws into it, and nothing marks the floor. You cut the foam inserts to your door's width, slide the sleeve into place, and you're done. When you move out, it comes with you.
Two-sided coverage is what separates this from a rolled-up towel. A single-sided stopper only blocks air on the face you put it on, and it slides away the first time the door swings. Because this one wraps under and grips both sides, it travels with the door. Owners consistently report it staying put through normal daily use.
